The reference numeral 1 indicates a metal base provided with an opening 2 in the top thereof. Rigidly mounted on the top of the base 1 are twooppositely disposed supporting frames or walls 3 and 4, each having an integral upwardly extending arm 5, shaped to afford shoulders 6. A vertical slot 7 is provided in each of the .frame arms 4, for

slidably receiving the grooved end portions of a transverse punch bar 8. AXially-formed on the ends of the punch bar 8, are trunnions 9, for receiving the upper'end's of connecting or driving rods 10. Journaled in the side frames 3 and 4, are the ends of a transverse horizontal shaft 1l, ron the middle portion of which is secured a pulley wheel or fly-wheel 12, adapted to be driven by a belt or other suitable means. Keyed or otherwise secured on the projecting ends of the shaft 11, are eccentrics 13, which engage in openings in the lower ends of the rods 10. Washers 14 and nuts 15 are used for retaining the rods 10 in position on the trunnions 9 and the eccentrics 13. f

Pivotally connected to one of the rods 10, is one end of a linlr 16, the other end of which is pivotally connected to the middle portion of a lever or arm 17. rlFhe lever 17, has itsl upper end rotatably engaged on a stub shaft 18, secured to project outwardly from the side of the frame 3.' Rotatalole on said stub shaft is a bevel gear 19, to the outer side of which is rigidly secured a ratchet wheel 20, also rotatable on said stub shaft 18. A check pawl 21 is vpivetally mounted on the outer side of the frame 3, to

fall by spring pressure into engagement with the teeth of the ratchet wheel 20, to prevent a reverse rotation thereof. Secured on the lower end of the lever 17, is a driving pawl 22, the end of which is engaged with the toothed periphery of the ratchet wheel to actuate the same when the lever 17 is operated; Secured on the outer surface ofthe frame 3, are bearings 23, for rotatably supporting a horizontal shaft 24. Keyed or otherwise'secured on one end of the shaft 24, is a bevel pinion 25, which is in mesh with the bevelgear 19, to receive a drive therefrom. Secured on the other end of the shaft 24, is a worm 2G, which meshes with a worm-wheel 27, secured on the outer end of one ofthe trunnions 28, which are provided at the ends of a master or driving roll 29. The trunnions 28, are journaled in suitable openings provided in the frames 3 and 4. Mounted on theother roll trunnion 28, to the outside of the frame 4, is a gear 30, which is adapted to mesh with a similar gear 31, secured on one of the trunnions 32, of an upper feed roll,y 33. 'She'upper lfeed roll trunnions 32, project through vertical key-hole slots 34, provided in the frames 3 and 4, as shown in Fig. 10, to permit vertical adjustment of said upper roll 33. Vertical drillings are provided in the frames 3 and 4, for receiving blocks 35, which are adjustably'V held against the trunnions 32, by springs 36, and adjusting cap screws or bolts 37, provided with loclr nuts 38.

Journaled in the frames 3 and 4, adjacent the upper feed roll 33, is a guide roll 39. Also journaled in the frames 3 and 4, to the inside of the guide roll/39, and in the same horizontal plane therewith is a switch or contact roll comprising a cylindrical metal core 40, and an outer cylindrical upper ,contact sleeve 41, which is insulated from the core 40, by a sleeve of insulating material 42. As clearly shown in Fig. 3, guide rolls 43, 44, 45, 46 and 47 have the trunnions thereof journaled in the frames 3 and 4. The guide rolls 43, 46 and 47, are disposed in the same horizontal plane with the rolls 33, 39 and 41, while the rolls 44 and 45 are positioned in a plane above the rolls 43 and`46. A perforatedy master music roll ribbon or strip 48 yis trained to run over `the upper feed roll 33, around the bottom of the guide roll 39, and up over the contactsleeve 41, then around the roll 43, and back 'again be low the sleeve 41 and the guide roll 39, to

run between the feed rolls29 and 33. At the feeding or entrance end of the machine a plurality of superimposed blank music roll ribbons or strips 49, kare fed'overY the roll 47, and between the guide rolls 47 and V46, then up over the rolls 45 and 44, from which point said ribbons are run between the rolls 44 and 43, and out of the machine between the driving rolls 29 and 33, completely perforatedV as hereinafter more fully described. Y

Projecting through the frame 3, is a binding post 50, which is insulated from said frame by an insulation sleeve or collar 51. Engaged on the inner end of said binding post 50, is a spring contact finger or brush 52, the .free end of which is positioned to frictionally ride on the contact sleeve. 41, as shown in Fig. 7. Connected to the binding post 50, is one end of a conductor wire 53, the other end of which is connectedV to a source of electrical energy, such as batteries 54a.

Rigidly secured on the upper edges of the frames 3 and 4, above the switch cylinder 41, is a cross strip or bar 54, to which is hingedly connected a mounting board 55, by means of hinges 56. The mounting board is hingedly mounted to permit access to be had to the under side thereof. Mounted in spaced relation on the mounting board 55, are a plurality of offset or staggered rows of binding posts 57, one post for each of the respective rows of note perforations of the master music roll. The capacity of the master -music roll 48, in this instance is arranged for ninety-nine rows of perforations, so that there are ninety-nine Vbinding posts 57 on the board 55. Each bindingl post 57 has connected to the lower projecting end thereof one end-of a resilient or spring contact member or brush 58, the curved free end of which is adapted to ridev over the master music roll ribbon 48, to track in itsy corresponding longitudinal row of note perforations. The solid portions of the master musicnroll ribbonpact'ft'o insulate or breakl the contact between the contact sleeve 41, andthe res ectivecontact brushes 58.

lupported on the frameshoulders 6, and byfmeansof postszor legs5'9, are two apparatusrboardsor tables 60, r`positioned on opposite sides ofthe frame farms 5. Mounted on the under side of the tables 60, are a plurality of staggered or offset rows of solenoids 61, oneffor each of the corresponding binding posts 57. The capacity of one of the ytables 60, is for forty-nine solenoids, while the other table has fifty solenoids mounted thereon. Each' solenoid 61 is provided with a soft metalcore 62, to the upper end of which is pivotally connected the lower end of a link 63. The upper end of each link 63, is pivotally connected to one end of a bell crank 64, which is supported on the tableby a slotted block 65. Pivoted to the other arm of each bell crank 64, is one end of a connecting rod or pin bar 66, to the end of which ispivotally secured a pin 67. The pins 67, slidably projectinto horizontal pin-ways Vor drillings `68,provided in opposite sidesof the punch bar 8, as shown in Fig.A 5. Alsov provided in the punch bar 8, are a plurality of vertical knife-ways or punch-ways 69, which cross the respective pin-ways 68. Referring to the wiring diagram ofA Fig. 13, it willbe seen that one terminal of each solenoid is connected to its respectve binding post 57, by a conductor wire 70, while the other solenoid terminal is connected by means of a conductor wire 71, to the batteries 54.

The perforating mechanisms are disclosed in detail in Figs. 4 and 5. Secured in the. bottom portions of the vertical frame slots 7, by means of bolts 72, are the ends of a platen 73, provided with a row of vertical drillings or openings 74. Secured on the upper surface of the platen 73, is a die plate 75, having a row of die openings 7 6, therein which register with the platen openings 74. An apertured stripper plate 77 is separated from the die plate 75, by spacer blocks 78. A. space 79, is thus afforded between the die plate 75 and the stripper plate 77, tov permit the music roll ribbons 49, to pass between said die plate 75, and the stripper plate 77. Spacer blocks 80, are supported on the end portions of the stripper plate 77, to space an apertured top or upper knife guide plate 81 above the stripper plate.V The retaining bolts 72 are threaded into the frames 3 and 4, for securely holding the platen 73, the die plate 75, the stripper plate 77, and the upper knife guide plate 81, secured in position. Hung below the punch bar 8, by means of bolts 82 is an apertured lower knife guide plate 83, which is spaced from the punch bar by means of spacer sleeves or collars 84, engaged around the bolts 82 between the punch bar and said lower guide plat'e83. A plurality of punches or knives 85are provided for doing the perforating. In this case, ninety-nine. knives are provided in arow. Each knife 85, is provided with a collar 86, at about the middle portion thereof and between the stationary guide plate 81 and the movable guidev plate 83. Asshown in Fig. 4, the knives 85 slidably project through the stationary guide plate-81, upwardly into the punch bar openings 69. The lower or cutting ends of the knives 85, slidably project through the'movable guide plate 83, and the stripper plate 7 7, for coaction with the openings 76, in the die plate 75, and the openings 74, in the platen 73. l

The operation is as follows:

With the improved music roll perforating machine constructed as shown and described, a plurality ofy blank music roll sheets or ribbons49, disposed one above the other, may be simultaneously cut or perforated to duplicate the perforations in master music roll sheet or ribbon 48, which is conducted around suitable rolls and discharged from the machine together with the plurality of perforated superimposed ribbons which entered the machine in blank form.

A As shown in Fig. 3, the perforated master music lroll ribbon 48, enters the machine over the Lipper feed roll 33, passes beneath the'idler or guide roll 39, and up over the switch or contact cylinder or sleeve 41, which is connected to one side of the bat* teries 54a, by means of the brush 52, and the wire 53. From the switch cylinder 41, the master ribbon 48 is trained around' the roll 43, and passes out ofthe same end of the machine between the feeding rolls 29'and 33.

A drive is imparted to the primary driving or feed roll 29, from the main pulley or iiywheel 12, which is adapted to be rotated by means of a belt from any suitable source of power. Rotation of the pulley 12, causes rotation of the shaft 11 andthe eccentrics 13, which being rotatable in openings in the lower ends of the arms or rods 10, act to reciprocate the sameto alternately raise and lower the punch bar 8. The eccentric movement of the rods 10, acts to swing the `lever 17, back and forth by means of the link 16. The swinging movement of said lever 17, causes the driving pawl 22 to engage the teeth of the ratchet wheel 20 and thereby rotate the ratchet wheel and the bevel gear 19 secured thereto. Thebevel pinion 25, in mesh with the bevel gear 19, is thus rotated, thereby causing rotation of the shaft 24 and the worm 26. The worm 26 rotates the worm wheel 27, and a drive is thus imparted to the main or lower driving or feed roll 29. The, gear 30, connected with the roll 29, drives the gear 31, and thereby causes rotation of the upper roll 33. The music roll ribbons are thus fed through the machine over and between the respective rolls as hereinbefore described. The feed rolls 29 and 33, and the punch bar 8, are thus operated simultaneously from the same source, namely the pulley wheel 12.

Referring to Figs. 3 and 7, it will be seen that all of the switch brushes or fingers 58, ridev over the surface of the perforated master ribbon 48, in position to track in the respective lines of apertures and slots covering the eighty-eight notes of a player piano. As the master ribbon passes over the switch cylinder 41, and below Vthe brushes l58, the brushes project through the master openings in the ribbon 48, and contact the switch cylinder 41. Circuits are thus closed with the respective solenoids 61, as will be apparent from the circuit diagram shown in Fig. 13. The respective solenoids 6l, are thus energized and act to draw the respective solenoid cores 62, upwardly thereby moving or tipping the respective bell crank 64, into the dotted line position of F ig. 12. The respective pin bars 66, are `thus moved inwardly toward the punch bar 8, thereby causing the respective pins 67 to enter the pin-ways 68, crossing the punch-ways 69, to serve as stops against which the upper end of the punches or knives 85 abut to prevent upward sliding of said knives in the punch bar ways 69. Downward movement ofthe punch bar 8, causes the inwardly projecting pins 67, to

force the respective knives 85, downwardly whereby the lower or 'cutting ends of said respective knives 85, cut through or punch the plurality of superimposed blank ribbons 49, which pass through the opening 47, between the stripper vplate 77, and the die plate 75, as shown in Fig. 4. With the return or upward movement of the punch bar 8, the movable guide plate 83, engages the collars 86, of the depressed knives and acts to retractor elevate the knives from their cutting or punching positions. The plate 77 acts to strip the perforated ribbons 49, from the knives 85, when the punch bar 8, returns to its upper position.

The operation of thesolenoids are con-V trolled by the switch brushes 58, which coact with the openings in the master music roll ribbon 48, to cause the proper knives 85, to be depressed by the punch bar 8, to out or punch apertures or openings in the ribbons 49, to duplicate the perforations in the master music roll ribbon. Either a single cut or a plurality of successive cuts may be made by a knife to providesingle circular openings or elongated slots in the ribbons 49. A plurality of music roll ribbons may thus be simultaneously cut or punched to duplirolls 29 and 33. The operations of the solenoids govern the operations of the cutter knives 85, by means of the pins 67, sinceY the make and break contacts of the brushes 58, with the contact cylinder 41, completely control the opening and closing ofthe electrical circuits to the solenoids.

It will, ofcourse/,be understood that the number of binding posts 57 and the number of solenoids may vary to correspond to the number of notes to be recorded on themusic roll ribbons, the capacity of which vary with the size of the player piano key-boards.

As described, ninety-nine binding posts 57, are provided on the contact board 55. Eighty-eight of the binding posts are used for the eighty-eight notes in a player piano, while the remaining binding posts are used for expression levers and other purposes. l

I am aware that many changes may be made, and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.
